To 



REV. MARK HOPKINS, DD., LL.D., 



PRESIDENT OP WILLIAMS COLLEGB. 



SIR It is not as a mere formality, nor from a desire to connect my name with 

 one so distinguished in the higher departments of Philosophy, that I inscribe these 

 Lectures to you. It is especially fitting that I should now acknowledge my indebt- 

 edness to you for tlxat kindness which is the most pleasant remembrance of my 

 student life, and which has remained unchanged through all the relations of fifteen 

 years of official labor. It was at your suggestion, that I first commenced a distinct 

 work on Natural Theology. It has taken its present form in the moments snatched 

 the varied duties that have daily demanded my time and strength. And 

 whatever may now be its value depends much upon the counsel and encourage- 

 ment which you have given me during the whole course of its preparation. 



With great respect and esteem, 



I am most truly yours, 



P. A. CHADBOURNE.
